What you need to know in advertising today

On Tuesday, a group of small advertisers added a complaint to a two-year lawsuit accusing Facebook of not reporting measurement problems for more than a year. The group claims that Facebook misreported an error in counting time spent watching videos.

While Facebook apologized in 2016 for measuring a metric measuring time spent with video incorrectly by 60% to 80%, the lawsuit claims the metric was inflated by 150% to 900% and that Facebook knew of the discrepancy for a little over a year.

Since then, Facebook has taken a number of steps to clean up its metrics, including putting together a measurement council and undergoing an audit from the Media Ratings Council to vet its metrics for third-party reporting. But it hasn't helped that on top of the metrics crisis, Facebook's also had to weather the Cambridge Analytica scandal and its recent hack of 50 million users.

These issues are collectively causing some marketers to lose faith in Facebook.
